bgirl123176 Can you load a different household within this save? Please test one or two, preferably households you've never played before.
If that works, evict your main household and place the sims on a new lot, then see whether you can load the sims on the new lot, or the lot without the sims.
Please also open Documents > Electronic Arts > The Sims 4 and delete any lastexception files you see. When you try to load a household and it doesn't work, look for a new LE. If you find one, open it, delete its first line, and attach it to a reply using the paper clip (Attachment) icon.
